TYPE-WRITINO MCHINE.

Original application filed August 26, 1913, Seria! No.- 786,693. Dividedand this 1914. Serial No. 839,673.

T all whom t 'may concern.' y

Be. it known that 1, OTTO PETERMANN, a citizen of the RepubliciofSwitzerland, and a resident of Groton, county of Tompkins, and State ofNew York, have invented certain new and usefullmprovements in-Type-Writing Machines, of which the following is a' full, clear, and exactdescription. Y

This invention relates more particularly to carriage stops for visibleor front-st ke typewriting machines and is a divisio of my pendingapplication, Serial No. 786,693, filed August 26, 1913.

One of the principal objects of the invenl5 Y tion is to provide'simpleand eiiicient means whereby a plurality of stops or devices may beadjustably supported at the rear of the carriage so as to move therewithand which are adapted to engage a part or parts Aof theV ;.inwhine notmovable with the carriage so that the carriage may be stopped at dierentpoints in its backward travel according to the position of said stops.

Another object of the invention is to pro- V vide a simple and efficientstop for typewriter carriages which is adapted to be vmade substantiallyentirely of sheet metal, as steel, and which is adapted to positivelylimit the movement of the carriage.

A further object of the invention is to provideffsimple and eiiicie'ntmeans whereby a plurality of stops may be mounted to rock on thecarriage in such a way that the carriage after being stopped may bepermitted to have a further movement when the stops are released.

lVith these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accom- 40 panyin'gdrawings, which form a part of this specification, and will then bepointed out l in the claims at the end of the description.

In the drawings, Figure 1 is a rear elevation of the upper part of oneform of typewriting machine showing the carriage and carriage bed withthe inventlonapphed thereto. Fig. 2 is an end elevation of` thecarriage. Fig. is a plan `View of the device or stopwith a part of itssupporting bar. i 4 is a detail perspective view of one of it stopsshowing how it is held to Specification of Letters Patent. l

its supporting bar; and F ig. 5 is a detail i perspective view showing aslightly differ! 13 of the carriage frame and on the outer end of theplaten shaft is a knob or button 14 by which the platen may be rotated,there -being the usual or any preferred formy of line-spacing mechanismprovided to rotate the platen as it is usua`l in typewriting machines.

A support or bar 15, which may be squareI 1n cross-section, extendslengthwise of thev carriage and has its ends pivotally held in the ends13of the carriage frame. At one end of the supporting bar 15 is a fingerlever 16 which is held to said bar and has a key 17 at its forward endto adapt sai'dwlever to be depressed to rock the bar 15 on itsl pivot.-'Y

The lever 16 has a part 18 extending rearward which is provided with anangular end 19, the said end being adapted normally to rest against therear edge of one of the carriage frame nds 13. This lei'er 1G as well asthe bar l5 is yieldingly held in its normal position by a spring 20, oneend of which spring is held to the bar 15 and the other end to thecarriage frame, said spring tending normally to force the end 19 of thelever 16 into engagement with the carriage frame. y i

The supporting bar 15 has a plurality of stops or devices 21, 22 and 23mounted thereon. These stops are exactly the same in construction exceptthat the stop 22 is Somewhat shorter than the other stops, and whileonly three stops are shown, there may be any desired number or only onemay be employed if preferred. These stops or devices may be variouslyconstructed. As `Shown, cach stop comprises two members 2l and Thelocking member 2t is provided .with a head 26 and the guiding mendaci'25 is provided with a head Q7. These members are made of fiat sheetmetal,l as' steel. formfd by dies or otherwise and the heads 213 and ZTare each substantially U-shapcd in plan. who

.head ci one member fitting within tbc other pso member in such a way asto permit, relative movement. The head 27 may be'called the guiding headfor the device and 26 lthe locking head. The bar '115 has apluralty ofvertically extending slots 28 which are' spaced apart, and' adapted toengage said slots is a dog or tooth 29 of the head 26.l The guiding head27 is provided with openings through the side plates or walls 30 ofsubstantially the same size and shape as the bar 15 in order that theentire device may be properly guided along the bar 15, while the head 25has an'opening longer than the bar 15 on the wall or side 3l only. Theside or wall 32 ofthe head 26 is relatively shorter thanthe 'side 31 andpermits said head 26 to span the head 27 and be guided properly thereby.The head 26 has a pendent part or arm 33 which is vSecured to the endentpart or arm 34'by va screw 35 or ot erwise. interposed between the armsor parts 33 and 34 and extends upward betweenithe heads 26 and 27 andnormally forces one of the headsalong the other and normally causes thedog or tooth 29 to engage one of the slots of the bar 15 so as to beheld to thebar-15in one of the adjustments of said stop; The head 26 isroughened, at 37, to provide a finger surface so that by pressing withthe iinger on the head 26, the tooth 29 may be disengaged from-one ofthe slots 28. and the entire device moved along the bar 15, and onreleasing the head 26 of any pressure by the finger, the device will belocked to the bar in any desired position..

A bracket 38 may be secured-by screws 39 or otherwise to the carriagebed 11 and may be provided with a projecting engaging portion or stop4:0V 4arranged in the path of the pendent arms of any one'o'f the stops21,22 and 23. The carriage may be moved along the bed 1l by the actionofthe letter spacing and tension means inthe usual way which will `causeone of the stops, as the stop 21 for example, to engage .the projectingpart40 ofthe bracket and hold the carriage against further movement.lever 16 is depressed to rock the bar 15 on its pivot, the pendent partof the stop 21 may be moved out of the path of the part 40 so that thecarriageV may havefurther movement. carriage, the pendent arm ofthe.stop 22 will engage the part 40 and lock the carriage against furthermovement unless released by'wocking the bar 15 when the carriage can bemoved farther backward and until the stop 23 engages said part 40, Thesestops may be of any desired number and may belocated at any'de'siredpart of the machine to adapt the stopsfor tabu1`ating or other purposes,and said stops may be made to engage a part of the bracket 38 or anyother desired part of the machine.

A fiat spring 36 is' the other.

If the arm or' On the return movement ofthe' In Fig. 5, the constructionis exactly the same as either of the stops described. except thatthespring 36 is dispensed with. In such case, the member 33 may be ofspring metal to permit relative movement of Vthe members 24; and 25. 'Aspiral spring instead .of aflat spring may be used and either kind ofspring may be employed with a spring part 33 if desired.

From the foregoing, it will be evident that'a simple and efficient stop=is provided; that a simple and eiiicient mounting for one or more stopsis provided whereby the said stops may be caused to hold the carriage'twomemberseach provided with a substantially U--shaped head, one movableon 'the' other and one of which isl adapted to engage the' member for'`adjustment thereon, Said heads having integral pendent portions'attached to each other to adapt one head to be moved relatively to theother.
